In the past few years, much attention has been drawn to the roller pump as a means of long-term assistance to the failing heart. During bypass, particularly left ventricular assistance, monitoring of the left atrial (LAP) and aortic pressures (AP) has been found to be essential for optimal regulation of the circulation. However, long-term catheterization of the left atrium or of hte descending aorta is undesirable, due to the inherent risks of infection, thrombosis, and hemorrhage. This research evaluates an original method of obtaining the LAP and AP during roller pump bypass, by means other than direct catheterization of the left atrium or of the aorta.
